The luminous cosmic ray emitting source at the center of our Galaxy, known as Sagittarius A*, is not a singularity as many astronomers and the unwitting mass media would have you believe.  Rather, it is a celestial orb that is about 4.3 million times the mass of our Sun and currently is seen, to radiate in the infrared about 20 million times the Sun's luminosity.  Its bolometric luminosity is estimated to be 2.5 billion solar luminosities, radiated in the form of cosmic ray electrons and protons (LaViolette, Subquantum Kinetics, 2012).  The cosmology of subquantum kinetics interprets Sgr A* as the Galaxy's Mother Star.  It is estimated to have a radius of about 21.6 solar radii which would give it an average density of 600 grams per cubic centimeter, or in other words, 600 times the density of water (LaViolette, Subquantum Kinetics, 2012).  Given that it has a mass of 4.3 million solar masses, Sgr A* would have a Schwarzchild radius measuring about 19 solar radii.  Its surface, however, lies outside its Schwarzchild radius and hence radiation can escape in all directions without a problem.
    Subquantum kinetics teaches that light could still escape from Sgr A* even if its surface were to lie inside its Schwarzchild radius.  Whereas general relativity teaches that light radiated within the Schwarzchild radius would be unable to escape to the outside world, subquantum kinetics does allow light rays to escape provided that they are not traveling parallel to the star's surface.  Since most light rays would be traveling either perpendicular or at a steep angle to the surface most should be able to escape.  
    In subquantum kinetics, there is no warping of space-time; space remains Euclidean.  Light bends because gravity causes the velocity of light to decrease.  As a result, the star's gravity field creates a light velocity gradient across the photon causing its trajectory to bend (or refract).  So, light rays originating from a Mother Star that is smaller than its Schwarzchild radius could escape to the outside, although, near the star's surface photons would be traveling at a velocity less than the free space velocity of light measured in the Earth's vicinity.  As they proceeded outward and emerged from the Mother Star's gravity well, their velocity would progressively increase toward our local c₀ value and this would correspondingly cause the wavelength of the photons to redshift.  This is why emission line radiation coming from active galactic cores is seen to be substantially redshifted.  This gravity-induced frequency shift effect has been observed near the Earth as an altitude dependent frequency shift effect, and is termed the Mosbauer effect.
    Unlike a conventional black hole, a Mother Star does not need to swallow matter in order to generate its enormous energy eflux. Rather, both energy and matter are spontaneously created within its depths seemingly in blatant violation of the First law of Thermodynamics (see below). The ensuing outward flux of radiation prevents the star's mass from unrestrained collapse.  So a black hole singularity would not form.  
    The gravity potential field around this Galactic core decreases inversely with increasing radial distance (G_p ~ 1/r), as shown above. Stars, gas, and dust orbit this body with velocities as high as 50% of the speed of light, but do not fall toward it. Gas and dust is instead seen to be moving radially outward from this source. After long intervals, the matter/energy generation process within the Sagittarius A* becomes unstable and it explodes with intense luminosity. Such galactic core explosions pose a potential threat to our planet.
    The First Law of Thermodynamics (in its most narrow interpretation) states that energy can neither be created nor destroyed, only interconverted from one preexisting physical form into another. The inherent flaw of this interpretation is that it presumes that there is no substrate of existence underlying the physical world of matter, energy and fields, i.e., no subquantum workings and no transmuting ether. If physicists wish to speak of ideas such as "zero point energy" or "quarks", the narrow interpretation of the First Law requires that this level of nature does not interact in any way with what takes place in our physical matter/energy world. Namely it perceives the physical universe as a closed system with no input or output changing its overall state.
    Although the narrow interpretation of the First Law may work well for explaining the workings of refrigerator appliances, it fails miserably when applied to matter and energy creation phenomena we see taking place in the cosmos. Here, very small departures from perfect energy conservation (far too small to measure in the laboratory) can produce very large scale effects such as supernovae or Galactic core explosions. These phenomena necessitate that we adopt a broad interpretation of the First Law, one that admits to the existence of an active subquantum etheric realm whose activity directly affects our physical universe. The physical universe is no longer viewed as a closed system, but as an open system, whose very existence depends on the continued activity of the subquantum realm. The First Law, then, may be more broadly interpreted as stating that the total system (quantum and subquantum) is conservative, but that when only considering part of the total, namely physical entities such as matter and energy, this subset may be nonconservative. One physics theory that conforms with this broad construction of the First Law is subquantum kinetics.
    So by realizing that there exists an underlying ether and that this ether functions as an open system, we may resolve the mystery of where the energy comes from that powers galactic core explosions. Like all open systems, the transmuting ether is able under certain circumstances to spontaneously generate order (matter and energy).
